The amount invested in the fund earning 8.5% is $40,000 whereas $20,000 was invested in the fund earning 10%
What is the return on each fund?
The return on each fund is determined as the amount invested multiplied by the interest rate on the fund
;Let X be the amount invested at 8.5%
Interest=8.5%*X=0.085X
The interest of the fund invested at 10%=($60,000-X)*10%
The interest of the fund invested at 10%=$6000-0.10X
Total interest=0.085X+6000-0.10X
Total interest earned during year 1=$5,400
5400=0.085X+6000-0.10X
5400=6000-0.015X
0.015X=6000-5400
0.015X=600
X=600/0.015
X=$40,000(amount invested at 8.5%)
amount invested at 10%=$60,000-$40,000
amount invested at 10%=$20,000

Answer:
Hotdog: $3.00
Hamburger: $4.00
Step-by-step explanation:
For the first time that Bob buys food, we can make an equation to find how much a single hotdog and a single hamburger costs, where:
x = cost of a hotdog
y = cost of a hamburger
He bought 2 hotdogs and 1 hamburger for $10, so the equation for his first time buying food is:
2x + y = 10
For the second time buying food, he bought 1 hotdog and 3 hamburgers for $15, so his equation would be:
x + 3y = 15
To find the value for x and y we need to solve this system of equations using the two equations we just came up with. We can do this multiple ways, but I'll be demonstrating the substitution method.
Using the second equation, we can solve for x by simply subtracting 3y from both sides:
x = 15 - 3y
We can then insert this value of x into the first equation so that way we are only dealing with one variable to solve - y:
2(15-3y) + y = 10
Distribute out the 2 into the paratheses, combine like terms, and then solve for y:
30 - 6y + y = 10
30 - 5y = 10
-5y = -20
y = 4
This means the cost for one hamburger is $4. But we still need to find the price of one hotdog, so we can insert this value of y into the equation we came up with earlier for x, and then solve for x:
x = 15 - 3y
x = 15 - 3(4)
x = 15 - 12
x = 3
So the price of one hotdog is $3 and the price of one hamburger is $4. Hope this helps.
